wtf?? when i plug it in and it show bootinglightning to 100% then after that it says The application is missing or corrupt... thats all it keep saying everytime i hook it up... it wont go to custom tune.
Go to dieblosport.com and try to download the last update to reload it. You may have to force the original tune back on it from a delership first, if your tune is corrupt. Hope it all works out for you buddy!
